lwmzntoz To all whom it may concern} Be itlmownthatl, Gnono'n -Gnoss,a" crtl:

zen of the United States, residing at Jean nette, in the count'y of Westmorelandand State of Pennsylvania have-invented a new,

and useful .Wrench,o l is a specification. r

. This invention relates to newfland 1 improvements in =9; ratchet-wrench; and

more particularly to a device of this character having 'means'for' permittin' ad ustnient of the head 'thereo fwith ire" ation to the handIe therebY; facilitating the use 0 the wrench incorn'er's, or-inlocations where the hand room is limited. H p I g A further object of the invention is i to provide means for lojckin g the head in such positions of adjustment, whereby the possibili-ty :of "the? head moving with'{ relation to its handle; isiabsolutely ehminatedm With the foregoing-and 'ther' objec tsb'iri" View of the wrench;

which. opening is formed to accommodate seat for the pin 19, which is of a length-to extend. beyond the inner wall of the head 7, to contact with the notches 20, formed in the 'jaw21, ofithe wrench. 1 1

From the foregoing it isobvious that due a ;,Within'the'head 7, and disposed a. one
